v1.7.0

## ECC v1.7.0 — Cross-Platform Expansion & Presentation Builder

**992 tests. 56 skills. 33 commands. 14 agents. 4 major coding harnesses.**

This release tightens ECC as a single source of truth across **Claude Code, Codex, Cursor, and OpenCode**, adds a full presentation-building workflow, and expands the repo with reusable content, research, and fundraising skills that are generic enough for any team to use.

### Highlights

- **Direct Codex support** — ECC now ships cleaner Codex app + CLI support with `AGENTS.md`-based setup, installer support, and Codex-facing docs
- **Cross-platform harness parity** — Cursor, Codex, and OpenCode support were expanded so the same repo structure works cleanly across all major AI coding tools
- **New `frontend-slides` skill** — Build animation-rich, zero-dependency HTML slide decks and convert PPTX workflows into web-native presentations with strict viewport-fit rules
- **5 new generic business/content skills** — `article-writing`, `content-engine`, `market-research`, `investor-materials`, and `investor-outreach`
- **Cowork marketplace compatibility** — Plugin manifests were reworked for Cowork compatibility and cleaner marketplace behavior
- **Chief-of-staff agent** — Added a communication-triage oriented agent for coordination-heavy workflows

### Skills Added In This Cycle

| Skill | Description |
|------|-------------|
| `frontend-slides` | HTML presentations, PPTX conversion guidance, style exploration |
| `article-writing` | Long-form writing, voice matching, guides, newsletters |
| `content-engine` | Platform-native repurposing for X, LinkedIn, TikTok, YouTube, newsletter |
| `market-research` | Market, competitor, investor, and technology research with sourcing |
| `investor-materials` | Decks, memos, models, fundraising docs, accelerator applications |
| `investor-outreach` | Investor cold emails, warm intros, follow-ups, and updates |
| `liquid-glass-design` | iOS 26 Liquid Glass design system |
| `foundation-models-on-device` | Apple on-device LLM integration patterns |
| `swift-concurrency-6-2` | Approachable Concurrency guidance for Swift 6.2 |
| `swiftui-patterns` | SwiftUI architecture and implementation patterns |
| `visa-doc-translate` | Visa and document translation workflow guidance |

### Platform and Workflow Improvements

- Improved Codex packaging and discovery
- Better OpenCode package/release alignment
- Cross-platform hook and path fixes
- Auto-detect formatter support in the post-edit hook
- Cleaner rule priority and development workflow documentation
- Better skill metadata traceability and distribution support

### Why This Matters

ECC is no longer just “a Claude Code plugin.” It now works as a **multi-harness operating layer** for modern AI coding environments while keeping the repo coherent enough to ship from one place.
